Jasper Library no compile with Parameter

[julioces]

hello,

 

I'm having the following problem: I have a report with sub report, where and passed as one parameter Collection. when I run into the iReports the resulado comes as planned, but when I run in my Java code, the following error appears:

 

Caused by: java.lang.ClassCastException: [Ljava.lang.String; can not be cast to java.util.Collection[/code]

 

the library version 5.5.1 and and my code that generates the PDF is:

 

InputStream is = this.getClass () getClassLoader () getResourceAsStream ("/" + filename)..;

JasperDesign jd = JRXmlLoader.load (s);JasperReport jr = JasperCompileManager.compileReport (jd);JasperPrint jp = JasperFillManager.fillReport (jr, parameters, jdbcTemplate.getDataSource () getConnection ().);

byte [] = pdfBytes JasperExportManager.exportReportToPdf (jp);return pdfBytes;[/code]

Is your "parameter" a "HashMap<String, Object>()"?
